Ajayendra V Tustin , CA April 10, 2015 Appliance: Model DUET SPORTS Had a f 01 error code Whirlpool Duet washer: My control unit blew because of a clogged drain. Had to open the bottom and cleared the drain ( 3 screws), then a f 01 code came and had to replace the ccu. Looked on line and had Coastal appliance next door which wanted the an extra $50 for the core and there price higher. Got the part from appliancepartspros.com and saved over $90 in parts alone. Used the back board of old unit as there was a little problem with 2 plastic tabs. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
